Custome cache key

[zdd]

Is it possible to use custome cache key instead of image url? since my image url including security tokens and the tokens will be expired after some time(1 hour for example) so the caching file will invalid too after 1 hour.

If this is possible, i can use the image url without the security token as the cache key to avoid token expired issue.
